You may get injured by glass fragments.
The electrode inside the main unit is made of glass.
Be careful not to break it.

Product handling information
Operational precautions
Use of the product in a manner not specified by the manufacturer may
impair the protection provided by the product. And it may also reduce
product performance.
Exercise the following precautions:
Use the supplied internal solution for the ammonia electrode. Using any
other internal solutions may cause measurement errors.
If the membrane of the glass electrode for pH measurement is dry, soak
the membrane of the glass electrode for pH measurement in the internal
solution for at least 12 hours. Using it in a dry state will cause
measurement errors.
Do not get the electrode connector wet or touch it with dirty hands. It may
cause a failure.
Do not touch a hard surface with the electrode. It may cause a failure.
Only use the product including accessories for their intended purpose.

About this product
Product features
The ammonia electrode is configured by a glass electrode for pH
measurement, a support pipe, and a membrane cap. The tip of the glass
electrode for pH measurement is made of a pH glass ion selective
membrane, and the tip of the support pipe has a membrane cap provided
with a membrane attached to it.
This product has the following features.
Ammonium ion concentration can be measured with this one electrode.
The ammonia electrode consisting of membrane and liquid junction of
the glass electrode for pH measurement has a double junction structure.
This minimizes the interference on the electrode potential caused by the
entry of gas into the internal solution.
System configuration
This product is used with the meter of HORIBA Advanced Techno
connected, which is sold separately.
Electrode stand(*) is also available.
